Export the waveform to your workspace as
a structure, to a .mat or a .bb file, or
to a runnable MATLAB® script.

Note

You can use the MATLAB script to reproduce your waveform outside of the
Wireless Waveform Generator app.

Generate a waveform that you can
transmit using a connected lab test instrument. The app can transmit using
instruments supported by the rfsiggen function. Use of the transmit feature in the app
requires Instrument Control Toolbox.

Examples

Generate WLAN HE SU PPDU

Open the Wireless Waveform Generator app and configure a
high-efficiency single-user (HE SU) PHY protocol data unit (PPDU). Using this feature of
the app requires the WLAN Toolbox™.

In the Waveform Type section, select
802.11ax. To generate the waveform, click
Generate. The displayed waveform is an HE single-user (SU)
packet with a 20 MHz channel bandwidth.

Generate WLAN HE ER SU PPDU with Packet Extension

Open Wireless Waveform Generator and configure an HE
extended-range (ER) SU PPDU. Using this feature of the app requires the WLAN Toolbox.

In the Waveform Type section, select
802.11ax. Configure the app to generate an HE ER SU PPDU
with two packets, specifying a delay of 50 microseconds between packets. Specify two
transmit antennas, and a nominal packet padding of eight microseconds. Click
Visualize and configure to select Time
Scope only. To generate the waveform, click
Generate.

Generate WLAN HE MU PPDU

Open Wireless Waveform Generator and configure an HE
multi-user (MU) PPDU. Using this feature of the app requires the WLAN Toolbox.

In the Waveform Type section, select
802.11ax. Configure the app to generate an HE MU PPDU, six
transmit antennas, six users, and a channel bandwidth of 80 MHz by setting the
allocation indices. For more information on setting allocation indices, see Multiuser HE Transmission. Enable high Doppler, midamble
periodicity of 10 symbols, and Fourier spatial mapping for each resource unit (RU). To
generate the waveform and display the resource RU allocation, click
Generate.

To get more information about an RU, you can click on its depiction in the
RU & Subcarrier Assignment tab.

To visualize the waveform, click Visualize and select
Spectrum Analyzer.

Generate WLAN VHT PPDU

Open the Wireless Waveform Generator app and configure a
very high throughput (VHT) PPDU with one packet and an idle time of zero. Using this
feature of the app requires the WLAN Toolbox. In the Waveform Type section, select
802.11n/ac (OFDM). To generate the waveform, click
Generate. The displayed waveform is an 802.11ac™ packet with an 80 MHz channel bandwidth.

Configure the app to generate a VHT PPDU with two transmit antennas, two users, two
packets, and an idle time of 0.5 ms between consecutive packets. Click
Visualize and configure to select Time
Scope only. To generate a waveform using the current configuration, click
Generate. The Time Scope plot shows the
updated waveform with two packets. An idle time of 0.5 ms follows each packet.

Note

The app only plots the first transmission stream.

Generate WLAN Single-Carrier DMG PPDU

Open the Wireless Waveform Generator app and configure a
directional-multi-gigabit (DMG) PPDU with one packet and an idle time of zero. In the
Waveform Type section, select 802.11ad.
Specify single-carrier modulation. To generate the waveform, click
Generate. The displayed waveform contains two 802.11ad™ packets.
